Question

jaundice is the abnormal yellowish - tint of tissues, such as the sclera of the eye. jaundice is due to the accumulation of what substance?

multiple choice

cholesterol

hemoglobin a

carotene

bile pigments

Explanation:

Jaundice occurs when there is an accumulation of bile pigments (bilirubin). Bilirubin is a yellow - colored substance formed from the breakdown of hemoglobin. When the liver cannot process bilirubin effectively (due to liver disease, obstruction of bile ducts, etc.), bilirubin accumulates in the blood and is deposited in tissues, causing the yellowish tint seen in jaundice. Cholesterol is a lipid involved in cell membrane structure and hormone synthesis. Hemoglobin A is the main type of hemoglobin in adults and is responsible for oxygen transport. Carotene is a pigment found in plants (like carrots) and excessive intake can cause a yellowing of the skin (carotenemia), but it is not related to jaundice.

Answer:

Bile pigments
